Description

Display panel and display device

Technical Field

The application belongs to the field of display, and particularly relates to a display panel and a display device.

Background

An OLED (Organic Light-Emitting Diode) display panel has the advantages of Light and thin structure, bending realization, high brightness, low power consumption, fast response, high definition, wide color gamut, and the like, and is increasingly used in electronic devices such as televisions, mobile phones, notebooks, and the like.

The active light emitting characteristic of the organic light emitting diode enables the OLED display panel to have a wider viewing angle, and the viewing angle can reach 170 degrees generally. The display panel has a wider viewing angle, so that better visual experience can be brought to users, but sometimes users also want the viewing angle of the display panel to be adjustable, so that business confidentiality and personal privacy are effectively protected, and business loss or embarrassment caused by screen information leakage is avoided.

The existing peep-proof display panel can only be torn away from the peep-proof film when the peep-proof film is not needed, and the peep-proof function is inconvenient to switch. In order to solve the problem that the peep-proof function of the switch is inconvenient, peep-proof pixels and shielding structures are arranged in some display panels, after the peep-proof pixels are opened, light of the peep-proof pixels is shielded by the shielding structures when the peep-proof pixels are watched at a small visual angle, the display panels can normally display, and when the peep-proof pixels are watched at a large visual angle, light emitted by the peep-proof pixels passes through the periphery of the shielding structures to interfere the light of the display pixels, so that peep-proof at the large visual angle is realized. The shielding structure occupies the design space of the display pixels, reduces the aperture ratio of the display panel, and particularly has more obvious aperture ratio loss when the large-angle peep prevention is required to be realized.

The driving circuit layer 200 is formed on a side of the substrate 100, and the substrate 100 includes a glass substrate or a polyimide (Pi) substrate.

The light emitting layer 330 is formed on a side of the pixel defining layer 320 away from the substrate 100, where the light emitting layer 330 includes a plurality of sub-pixels, the sub-pixels are connected to the anode 311 in a one-to-one correspondence manner, the plurality of sub-pixels include a plurality of display sub-pixels 331 and a peep-proof sub-pixel 332, the plurality of display sub-pixels 331 are located in a plurality of display pixel areas in a one-to-one correspondence manner, each display sub-pixel 331 is connected to an anode 311 in a corresponding manner, the peep-proof sub-pixel 332 is located in a peep-proof pixel area in a corresponding manner, and each peep-proof sub-pixel 332 is connected to an anode 311 in a corresponding manner.

It should be noted that the plurality of display sub-pixels 331 may include a red display sub-pixel R, a green display sub-pixel G and a blue display sub-pixel B, but the present invention is not limited thereto, and the plurality of display sub-pixels 331 may be all white sub-pixels W or sub-pixels of other colors, as the case may be.

The thickness direction of the display panel is a longitudinal direction, and the length direction of the display panel is a lateral direction (horizontal direction in the drawing). The larger the peep-proof angle to be realized, the larger the lateral boundary of the light shielding unit 361 exceeds the lateral boundary value (i.e., X in fig. 3) of the peep-proof sub-pixel 332, the larger the space occupied by the light shielding unit 361 by the display panel, and the larger the aperture ratio loss of the display panel.

The front projection of the sagging portion 3612 on the substrate 100 is located outside the front projection of the peep-preventing sub-pixel 332 on the substrate 100, that is, in the case that the lateral dimension of the peep-preventing sub-pixel 332 is unchanged, the lateral dimension (i.e., Y in fig. 3) of the sagging portion 3612 may be designed to be longer and smaller, so that the breakage of the encapsulation layer 350 may be reduced, and the encapsulation quality of the display panel is not affected.

Referring to fig. 1 and 2, the display panel further includes a color resist layer 370 and a light shielding layer 360, wherein the color resist layer 370 includes a plurality of color resists, and the orthographic projection of the display sub-pixel 331 on the color resist layer 370 is located in the color resists.

In addition, the display panel further includes an anti-reflection layer 380, and the anti-reflection layer 380 is formed on a side of the color resist layer 370 remote from the substrate 100.

In order to improve the contrast ratio of the display device and realize an integral black effect, a Polarizer (POL) is generally adopted in an OLED display panel, and the polarizer can effectively reduce the reflection intensity of external environment light on a screen. However, the light transmittance of the polarizer is generally only about 44%, and more power consumption is required to achieve higher light-emitting brightness. In addition, the polaroid has larger thickness and crisp material, and is not beneficial to the development of dynamic bending products.

The structure of color resistance, black matrix and anti-reflection layer 380 is adopted, red color resistance, green color resistance and blue color resistance filter light, the black matrix is arranged around the color resistance to shield light, the anti-reflection layer 380 reduces the reflection intensity of external environment light on a screen, the polaroid of the OLED display panel can be canceled, the thickness of the functional layer is greatly reduced, the light emitting rate can be improved from 44% to 80%, the light emitting brightness is greatly increased, and therefore the power consumption of the OLED display panel is reduced.

Referring to fig. 1 and 2, the light shielding unit 361 is disposed in the same layer as the black matrix.

It should be understood that "co-layer arrangement" in this application refers to a layer structure in which a film layer for forming a specific pattern is formed by using the same film forming process and then formed by using the same mask plate through a one-time patterning process, that is, one patterning process corresponds to one mask plate (also referred to as a photomask). Depending on the particular pattern, a patterning process may include multiple exposure, development, or etching processes, and the particular patterns in the formed layer structure may be continuous or discontinuous, and may be at different heights or have different thicknesses. Therefore, the manufacturing process is simplified, the manufacturing cost is saved, and the production efficiency is improved.

The second inorganic encapsulation layer 353 has a thickness of 0.5 to 2 microns, with a preferred thickness of 0.8 microns.

The inorganic encapsulation layer has better water-oxygen blocking effect than the organic encapsulation layer 352, and the second inorganic encapsulation layer 353 is arranged between the organic encapsulation layer 352 and the cathode layer 340, so that the sagging portion 3612 can be prevented from influencing the encapsulation quality of the display panel.
